Learn more about knitting gauge

Gauge is perhaps the most critical element for success with a knitting project. Many skip the test swatch because they're eager to get started, but this can lead to the sweater being either much too large or much too small.

Did you know that even a difference of 1-2 stitches per 10 cm can make over a 10-centimeter difference in circumference on a sweater? This is why professional knitters always prioritize checking the gauge before casting on a new garment.

How to count stitches accurately

Use a gauge ruler or a standard measuring tape. Place it in the middle of your swatch, away from the edges, as edge stitches are often uneven. Count the number of full and half stitches over exactly 10 cm. Do this in several places on the swatch to ensure a representative average.

Why doesn't my gauge match?

Many factors affect your gauge. Your personal tension is the most important, but the material of the needles (wood vs. metal), how you hold the yarn, and even your mood can play a role. If you're stressed, you often knit tighter!

Also remember that different yarn types have different elasticity. A pure wool yarn will behave very differently from a cotton or silk yarn, even if they have the same yardage. This is why the gauge calculator is an indispensable tool every time you start a new project or change yarn quality.

Tips for a perfect swatch

• Cast on enough stitches: Always cast on 10-15 more stitches than what is specified per 10 cm. We want to measure in the middle of the swatch.
• Knit high enough: The swatch should be at least 12-15 cm high for the stitches to "settle."
• Wash and block: This is the most important step many skip. Wash the swatch as you plan to wash the finished garment. Check out our Washing and Care Guide for details.
